Security Term

Credential Stuffing

An automated attack in which stolen username and password combinations are tested against multiple services to gain unauthorized access.

What is Credential Stuffing?

Credential stuffing exploits password reuse — the common habit of using the same credentials across multiple accounts. Unlike brute force, it uses real credentials from data breaches, making it harder to detect. Multi-factor authentication is the most effective defense.

Understanding this concept is crucial for maintaining a robust security posture. In the context of modern cyber threats, credential stuffing represents a significant area of focus for security professionals and organizations alike.
